Always switch off your system before disconnecting any wires.
To increase the versatility of connecting up, the SerieT/i models have three separate inputs. A Neutrik®
Speakon® socket and two phono sockets. This is to facilitate use with both two-channel stereo systems and
AV surround sound systems.
The high-level, unbalanced, dual-channel (stereo) input is via a Neutrik® Speakon® connector which is
connected to the power amplifier’s left and right channel speaker terminals. This has the advantage of
ensuring that the REL receives exactly the same signal as the main speakers. This means that the character
of the bass from the main system is carried forward into the sub-bass. This is a very important point and
together with the REL’s Active Bass Controller (ABC) ensures far superior system integration of the sub-bass
with the main system.
The low-level input is via two separate phono jacks that connect to either the .1/LFE output of a home
cinema amplifier/processor or to the output of a stereo preamplifier.
HI LEVEL and .1/LFE inputs can be used simultaneously. The benefits are two-fold when used with a home
cinema system. The low level input reproduces the .1/LFE channel and the high level connection underpins
the main front speakers. The main front speakers should be set to the ‘large’ option on the processor. See
“Theater Applications” for more information.
Connecting to the Power Amplifier Using the Speakon® High Level Input
To engage the Neutrik® Speakon® plug, insert fully into socket and rotate clockwise until locked.
To remove the Neutrik® Speakon® plug, grip body of plug, place thumb on chrome lever, move lever backwards,
rotate plug anticlockwise quarter turn and withdraw.
The high-level input is designed to accept the stereo (two-channel) signals from the speaker terminals of
your receiver, integrated amplifier or basic amplifier. This has the advantage of ensuring that your subwoofer
receives exactly the same signal as the main speakers, which means that the character of the bass from the
main system is carried forward into the Sub-Bass System.
This is a very important point and together with REL’s Natural RollOff™ circuitry, ensures far superior system
integration of the Sub-Bass System with the main system.
High-Level Input:
Connections should be made to the same binding post on main amplifier as the main

speakers. Red to amplifier main right speaker red terminal, yellow to amplifier main left speaker red terminal
and black to amplifier main speaker black terminal, right or left but not both. Plug the Neutrik® Speakon®
plug into the HI LEVEL Speakon® socket.
.1 Input:
This requires a phono-to-phono cable and is a dedicated true .1 channel. This circuit therefore
eliminates the normal Natural RollOff™ Crossover and passes the .1 low-level signal through with only the
required 120Hz fourth-order filter.
Low-Level Input:
The phono input allows for conventional connection from a preamplifier and should be
used in the rare event that a high-level connection proves incompatible. Plug one end of the phono-phono
cable into the LOW LEVEL INPUT jack of the REL and the other end into the left or right channel output of
your preamplifier.
PHASE SWITCH
– Used to set phase
Position 0 / High-Level, Low-Level or LFE: 0 degrees phase
Position 180 / High-Level, Low-Level or LFE: 180 degrees phase
PHASE SELECTION AFFECTS BOTH HIGH- AND LOW-LEVEL INPUTS
Crossover is always engaged for Hi level input. The .1/LFE signal does not pass through the crossover circuit.
